HAND-THREADING SHUTTLE.

Specification of Letters Patent.

Patented Dec.10,1912.

Application filed. February 7, 1912. Serial No. 676,009.

To all whom it may concern:

Be it known that I, ADELARD HOULE, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Hand -Threading Shuttles, of which the following is a specification.

This invention pertains to certain new and useful improvements in hand threading shuttles, and the primary object of the invention is to provide improved means of simple, and inexpensive nature, which will allow of easy threading of the shuttle, and which will positively hold the thread against accidental unthreading in the shuttle movements.

In the drawings; Figure 1 is a fragmentary top' plan view of a shuttle constructed in accordance with the present invention; Fig. 2 is a fragmentary side elevation; Fig. 3 is a perspective View of the threading device detached from the shuttle; Fig. 4 is a section taken on the line 4-t of Fig. 3; Fig. 5 is a similar view looking at right angles to Fig. 4E; and Fig. 6 is a plan View of the fabric lining.

In proceeding in accordance with the present invention, I employ a sheet metal plate or strip 1 that is inset in a side of the shuttle, and secured therein by means of set screws 2, as clearly depicted in Fig. 2, of the drawings. At one side of the plate 1 in spaced relation and at right angles thereto is located a block 3, which has connection with the plate 1 by means of a looped bar 1 which has its free end extending through an opening provided therefor in the block and clenched therein, the opposite end of the bar being integrally connected to the end wall formed by a slot 5 in the plate 1. The point of connection between the loop bar 4 and the plate 1 is disposed between the top and bottom sides of the slot 5. The block 3 is formed with a vertically diagonally disposed slot 6 whose lower end leads into a circular eye 7 formed transversely through the block 3. The block 3 is held in position by means of a pair of vertical pins'8 that extend through openings 9 formed in the block 3 and are secured to the shuttle body.

By reference to Fig. 1 of the drawings it will be seen that the block 3 extends transversely across the throat of the shuttle and the looped part of the bar 4: extends upwardly at an incline as shown in Fig. 4 and overlies a fabric lining 10, which is preferably formed of felt in the shape shown in Fig. 6 of the drawings. The purpose of the felt lining is to enable the shuttle to be easily threaded and to prevent the thread from coming in contact with the wood in the throat of the shuttle.

'In operation the thread is first placed in the slot 6 and is then moved to engage under the loop of bar 4: between the latter and the fabric lining 10, whereupon the thread is pulled in a direction toward the rear and the delivery eye side of the shuttle which will cause the thread to ride down under the leg of the bar 4 that is connected with plate 1 which will bring the thread to the position shown in dotted lines in Fig. 2, in which position it extends up across the end of the leg of loop 4 that is disposed in slot 5, after which that portion of the thread that extends across said last mentioned leg of loop 4 is caught by the fingers of the operator and drawn. outwardly through the slot 5, to the posit-ion shown in full lines in Fig. 2 when it is ready for use.

What is claimed is:

1. In a shuttle, a plate secured to one side of the shuttle body and formed with a slot, 2. block arranged across the throat of the shuttle and formed with a transverse thread eye and an oblique slot that extends downwardly from the top face of the block into said eye, and a looped bar having one end connected to said block on the inner side of said eye thereof and having its opposite end secured to the inner end wall formed by said slot of the plate and located between the top and bottom walls formed by said slot.

2. In a shuttle, a transverse thread engaging device in the throat thereof having a thread eye, a longitudinally slotted plate secured in one side of the shuttle, and a looped bar having one end supported by said plate and disposed between the top and bottom walls formed by the slot thereof and having its opposite end supported by said thread engaging device on the side thereof between said eye and said plate.

3. In a shuttle, a thread engaging member in the throat therof, a slotted member in one side of the shuttle and a looped bar that has one end supported by said thread engaging member and has its opposite end supported by the slotted member and disposed between the top and bottom Walls formed by said slot thereof.

4. In a shuttle, a plate having a horizontal slot formed therein secured to one side of the shuttle body, a thread engaging member in the shuttle throat arranged at substantially right angles to said plate, said member having a thread receiving slot, and a looped bar integral With the plate and connected thereto adjacent said slot thereof 1- and having its opposite end passed through said member and clenched thereto.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ADELARD HOULE.
